Remeha Elga Ace issue - lukewarm radiators

[Barucchi]

Dear Tweakers, I am sorry but I am not so good in Dutch to write the techy questions in the forum.
I just installed Remeha Elga Ace Hybride Warmtepompen in combination with my Nefit CV (gas)
I still cannot get my radiators hot, like last year with gas only. Cannot get more than 20,5C and I can hear that the outside unit is on full speed. The pump is using about 35kWh/day.
My radiators are new in two rooms and 4 old ones in other 4 rooms

Any thoughts good people?

Is the Nefit doing anything?
The problem with hybrid heat pumps is usually that there no communication between the heat pump and the gas furnace. Either not wired correctly or settings not right.

Some pictures of your setup would be helpful, as well as any other details you can give. How big is the house? What type of radiators do you have, what are the (ingoing and outgoing) water temperatures of the heat pump? How many rooms are you heating, and what's the state of thermal isolation of the house?

Are you running the split version, or the monoblock?

Room temperature or radiator temperature?

The pump is using about 35kWh/day.

Is there any gas usage in addition to the heat pump's energy consumption?

Seems to me that communication is not right. Thanks for the point.
